The Arachnid!!! is an enemy in EarthBound that can be encountered throughout the Pyramid near Scaraba. Like its weaker brethren, Arachnid!, it can shoot spider silk from its body to immobilize a party member, or sting with its stinger to poison one target. It may spawn alongside up to three other Arachnid!!!, a Fierce Shattered Man, or a Guardian Hieroglyph.

It is intended to be identical to the Arachnid!!!!, as they share the same Japanese name with four exclamation points.
